Article Abstract
Unlabelled: This study from southern India showed that proximal hip geometry was significantly impaired in postmenopausal women with femoral neck fracture. The trabecular bone score (TBS), which is reflective of bone microarchitecture, was also significantly impaired in patients with fracture.
Introduction: There is limited information with regard to comprehensive bone health in Indian postmenopausal women with neck of femur fracture. We studied the bone mineral density (BMD), trabecular bone score (TBS), proximal hip geometry, and bone mineral biochemistry in postmenopausal women with and without femoral neck fractures.
Methods: This was a cross-sectional study conducted at a tertiary care center in South India. BMD, TBS, and hip structural analysis (HSA) were assessed using a dual-energy X-ray absorptiometry (DXA) scanner. Bone mineral biochemical profiles were also studied.
Results: A total of 90 postmenopausal women with acute femoral neck fracture with mean (SD) age of 63.2 (6.1) years and 90 age-matched controls were included. The prevalence of osteoporosis was higher among cases as compared to controls (83.3% vs 47.8%; P < 0.001). Degraded bone microarchitecture (TBS value < 1.200) was more frequent among women with hip fracture as compared to controls (46.7% vs 31.1%; P = 0.032). Cross-sectional moment of inertia (CSMI) was significantly lower at the narrow neck (NN) and inter-trochanteric (IT) region in cases (P < 0.05) and buckling ratio (BR) was significantly higher at all three sites in postmenopausal women with femoral neck fracture as compared controls. Multivariate logistic regression analysis showed that femoral neck osteoporosis, low CSMI at NN and high BR at NN and femoral shaft emerged as factors significantly associated with femoral neck fractures.
Conclusion: This study highlights that impaired parameters of proximal hip geometry and a low trabecular bone score may be significantly associated with femoral neck fractures in postmenopausal women.

Associations between breastfeeding and breast cancer risk through mammographic breast density in a cohort of Korean women.
Int J Epidemiol
December 2024
Department of Preventive Medicine, Hanyang University College of Medicine, Seoul, Republic of Korea.
Background: Mammographic breast density has been suggested to play a role as a mediator between the risk factors for breast cancer (BC) and BC risk. We investigated the extent to which never breastfeeding is a risk factor for BC and how this risk is further mediated by increased mammographic breast density.
Methods: This retrospective cohort study included 4 136 723 women aged ≥40 years who underwent mammographic screening between 2009 and 2010 and were followed up until 31 December 2020.
Diagnostic yield of upper gastrointestinal tract endoscopy and colonoscopy in patients with iron deficiency anaemia while on direct oral anticoagulants.
Intern Med J
December 2024
Internal Medicine Services, The Prince Charles Hospital, Brisbane, Queensland, Australia.
Background: Iron deficiency anaemia (IDA) related to occult gastrointestinal tract (GIT) blood loss is associated with high rates of GIT malignancies. Major society guidelines recommend bidirectional endoscopic evaluation for all men and post-menopausal women with newly diagnosed, unexplained IDA. However, in patients prescribed direct oral anticoagulants (DOACs), the endoscopic yield, specifically the rate of high-risk findings, including colorectal cancers (CRCs) and advanced adenomas (AAs), is unknown.

Background: Postmenopausal women represent the demographic increasingly susceptible to cardiovascular and metabolic diseases. Elevated levels of remnant cholesterol (RC) have been implicated in atherosclerosis and insulin resistance.
Methods: This study aimed to investigate the relationship between RC and the prevalence of coronary heart disease (CHD), diabetes, and CHD combined with diabetes in a nationally representative sample of US postmenopausal women using data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018.
Hormone Replacement Therapy in Post-Menopausal Women Undergoing Total Hip Arthroplasty is Associated with Reduced 10-Year Periprosthetic Femur Fracture Rate.
J Arthroplasty
December 2024
Department of Orthopedic Surgery, Johns Hopkins University, Baltimore, MD.
Introduction: In postmenopausal women who are estrogen deficient, hormone replacement therapy (HRT) has been shown to improve fragility fracture risk. However, few studies have examined the relationship between HRT and periprosthetic fracture (PPF) risk after total hip arthroplasty (THA). The purpose of this study was to determine the impact of HRT use on 10-year PPF risk following THA.

J Orthop Surg Res

Department of Endocrinology, Hebei Medical University Third Hospital, Shijiazhuang, Hebei, China.
Background: The influence of the glucagon-like peptide-1 receptor (GLP-1R) on bone metabolism is well-established. However, it has been observed that single nucleotide polymorphisms (SNPs) in the GLP-1R gene can partially affect its function. Therefore, this study aims to investigate the association between SNPs in the GLP-1R gene and postmenopausal osteoporosis (PMOP) within the Chinese Han population.
